Abstract


Steel-concrete composite beam has the advantages of both steel structure and concrete structure, and itwould has vast application prospect.However, we emphasize the security and applicability but ignore the durability of structure in structure design. But this would make the structure failure before it’s service deadline, and lead to a grate economic loss. Therefore, it is necessary to carry out the research on the steel-concrete composite beam attacked by salt solution, to study its deterioration rule and damage mechanism, so that to meet the requirements of social development, to ensure national economic development and reduce economic losses.This article aim at the problems in studying the steel-concrete composite beam, study the deterioration law and damage mechanism by dry and wet cycles quick corrosion experiment in chloride case. The main contents include:(1) This article aiming at there kinds section form of the steel-concrete composite beam, studys the route through which chloride ions into the steel-concrete composite beam by dry and wet cycles quick corrosion experiment, and finds the section form of the steel-concrete composite beam which can resist chloride ions invasion best.(2) The deterioration rule of the materials of the steel-concrete composite beam and the protection of durability are analyzed by dry and wet cycle’s quick corrosion experiment. The experiment will get the concrete of the distribution of percentage content of chlorine ion and law. Also it gets the stud, steel reducing coefficient of strength and the constitutive relation after corrosion. These provide base for the studying durability of steel-concrete composite beam after corrosion.(3) The push-out tests are carried out to study the behavior of the shear connectors attacked by salt solution. The mechanical characteristics of them, namely the anti-slip capability and the law of the ultimate bearing capacity, are investigated and compared with the behavior of the control specimen not attacked. More, we respectively simulate the push-out tests of the studs which are corroded or not by the finite element software of ABAQUS.(4) The experimental studys on the flexural performance of steel-concrete composite beams attacked by salt solution. The mechanical characteristics of them, namely the anti-slip capabilities, the cross-section strains, the cross-section deflections and the ultimate bearing capacities, are investigated and compared with the behavior of the control specimen which is not attacked.
